CP320 is a cold applied single pack, ultra high solids, moisture activated, elastomeric urethane containing inert reinforcement fibres. High elasticity allows membrane to “move” without cracking or splitting. Internal reinforcement often avoids the need to use dry reinforcement scrims, matting etc, on tight lap joints, bolt heads, etc.
Waterproofing membrane coating for protection of sound (small) flat and pitched roofs, etc. Also used as bridging stripe coat on firm lap joints, bolt heads, during refurbishment of profiled metal sheeted roofs.
- Not suitable for use in areas exposed to continuous chemical contamination.
- Not suitable for continuous foot traffic without the addition of suitable walkways or protection.
- Durable liquid applied coating providing guaranteed waterproofing
- Quick and easy to apply even around complex detailing
- Single component materials - no mixing required
- Fibre reinforced for extra strength and durability
- Primerless application to most common flat roof substrates

Preparation
- Primerless application to most common flat roof substrates
- Inspect roof surface and seal or repair any cracks or splits in the existing waterproofing.
- The roof surface should be cleaned using a pressure washer set at a maximum of 2,000 psi. Thoroughly wash the surface taking care to remove all loose material, sand, dirt and other materials.
- Once the surface is free from contaminants, apply a biocidal wash to the entire area.
- Remove any remaining surface water using a stiff brush or squeegee and allow the surface to dry.
